As the Fiedler Dolby Atmos Composer plugin isn't available in VST2 format, only VST3, we can't access the multi-outs to route to Dolby Atmos speaker setups internally with the DAW. The Composer does offer a way to route output to an external WDM interface, but this seems less than ideal, you really want to just use the hardware interface Bitwig is using and keep it all clocked together from the same audio interface.
If you set Fiedler Beam & Composer (VST3) + Plogue Bidule x16 (VST2) plugins to run in their own process in Bitwig, the Beam plugin still communicates with Composer even when Composer VST3 is being hosted in Plogue Bidule. As Plogue Bidule x16 is a VST2 plugin, we get to output up to the 9.1.6 of Composer internally within Bitwig and so then you will be able to use Audio Receivers to 16 ports on your audio interface and so onto your speakers.
